I've bricked my TP-Link TL-WR741nd and I've bought the PL2303 USB to RS232 adapter.
I have soldered on 3 wires to the motherboard, RX, TX and GND as it showed on the Wiki diagram. This is a v2.4 board. Anyways, the solders are not the cleanest ones but they *should* work.
However, when I plug in the adapter and open putty with the correct bit rate, I get a blank screen. I've checked if by any chance I've switched wires but all of them go from TX to TX, RX to RX and GND to GND.
I don't know what else to try.
Regards,
UPDATE: Here are a few images to show what I did...
